To all 'whom t may concern.'

Be it known that I, ROBERT H. HARRIS, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Shackles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shackles and the primary object of the invention is to provide a shackle particularly for use in ship building which is comparatively simple in construction and may be quickly and easily attached to or detached from a lining or armor plate of a ship for the purpose of hoisting the plate to its proper position on the side of the ship.

Another object of this invention is to provide a shackle base bar which has a hook formed upon one end and the other end flattened, and pivotally connected to the flattened end an arcuate member for coaction therewith and insertion through a rivet hole in an armor or lining plate for supporting the same during the hoisting of the same.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved shackle showing thel parts thereof in section and showing the same attached to the plate in dotted lines, and

Fig. 2 is a front view of the improved shackle.

Referring more particularly to the drawings, 1 designates the body portion of the shackle which has a hook 2 formed upon one end thereof by the bending or curving of the end of the hook 2 of the bar as is clearly shown in Fig. 1 of the drawings. The body 1 is flattened as is shown at 3, and has its lower end 4 sharpened or beveled for forming a sharpened knife like end. The iiat section 3 of the body 1 of the shackle is provided with an opening 5 extending transversely therethrough a short distance upwardly from the upper terminals of the inclined sides which form the knife like point 4. The opening 5 extends diagonally through the body 1 and is provided for receiving the end of the arcuate portion 6 of the pivoted hook member 7. The hook member 7 is pivotally and loosely connected to the body 1 by a bolt 8, which bolt is carried by the flat section 3 of the body 1, and extends transversely therefrom, extending through the flap 9. which is formed in the flattened end 10 of the hook member 7 The hook member 7 is held in firm abutting engagement with one surface of the flat section 3 of the body 1 by a nut ll of the ordinary type which is adjustably mounted upon the screw threaded end of the bolt 8. The member 7 has its upper end which is pivotally connected to the attened section 3 of the plate 1, flattened for rm abutting engagement with the section 3. The arcuate section 6 of the hook 7 is round in cross section and the terminal end 12 thereof is provided for extension through a rivet hole indicated at 13 in dotted lines, in the drawings, of an armor or lining plate 14 such as is ordi narily used in ship construction and also for insertion into the transverse inclined extending openings 5, where it is securely held by the tightening of the nut 11 upon the bolt 8, thus providing a quick and easy detachable shackle for use in hoisting plates to the desired position in ship building construction.

It is to be understood that the improved shackle heretofore described may be employed for any function whatsoever, and is not limited for use in ship building, and also that certain minor features of construction may be altered provided such alterations are comprehended within the scope of what is claimed.

What is claimed is 1. In a shackle, a body portion having a hookl formed upon one end thereof, the other end of said body portion being flat and provided with a transversely extending opening formed therein, and an arcuate member pivotally and laterally adjustably connected to said body portion, said arcuate member adapted for having its lower free terminal end inserted .through said transverse opening..

2. In a shackle, a body portion having one end thereof bent to form a hook, the other end of said body portion being flat and having the sides of'its terminal ends tapering for forming a knifelike inserting point, said flattened section being provided with a transversely extending opening formed therein a short distance upwardly of the upper terminals of the inclined sides of said inserting point, a transversely extending bolt carried by the flattened section of said body portion upwardly of said transverse opening, an arcuate hook member loosely mounted upon said bolt and having its lower end curved for insertion into and through said transverse opening, and means carried by said bolt for holding said arcuate hook member in firm connection to said body portion as and for the purpose described.

Intestimony whereof I afliX my signature in presence of two witnesses. n
